To all whom, it may concern:

. e it known that I, ERNEST M. WHITE, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Splash-Trough, of which the following 'is a-specification.

' case by the ends of theconnecting rods and conveying that oil to the next auxiliary receptacle 1n the rear or to the main receptacle; andthe object of this invention is to provide an efficient oil conveyer of this character that can be readily secured in position and that may be produced at low cost;

This invention consists in a series of oil troughs combined to form a separate unit adapted tobe secured to one side of the lower ortion of a crank case of a common type 0 internal-combustion vehicle engine sothat the oil splashed up by the connecting rods from small reservoirs in the bottom of the crank case will be carried rearwardly step by step to a main reservoir below the fly-wheel and formed by the fly-wheel housing, and thus prevent an excessive accumulation of lubricating oil, especially at the front end of the crank case when the vehicleis going down hill and thereby avoid overlubrication of the cylindbrs but especially of the front cylinder and the excessive depositv of carbon therein.

In the accompanying drawings, Figure 1 is a side elevation of a four-cylinder internal-cornbustion engine with a portion of the crank case broken away. Fig. 2 is an elevation of my improved splash trough secured in position. Fig. 3 is a transverse section of the lower part of the crankcase. Fig. 4 is a front e evation of the splash trough. Fig. 5 is a transverse section, through a modified form thereof Fig. 6 is a pers ective of one end of the reinforcing-bar orthe bottom portion of the crank case. Fig. 7 is aside elevation of a modified form of splash trough secured in proper position. Fig. 8 is a plan of the same. Fig. 9 is an end elevation of this trough. Fig. 10

is a section on the line l0l0 of Fig. 8 on a larger scale. Fig. 11. is a perspective of for the securing bolts for the troughs may be located.

Similar reference characters refer to like parts throughout the several views.

The engine shown in Fig. 1 is of well known construction, being used on theFord cars, and has a block 1 of cylinders united to the upper crank case 2. The lower crank case 3 is preferably of pressed sheet metal secured to the u per case by means of bolts 4:. The crank shaft 5 has cranks G, 7, 8, 9, 10 and 11 which receive thrust from the lower ends of connecting rods 13, It, 15 and 16. These connecting rods have downa templet by means of which the holes wardly extending bolts 17 and nuts 18 adapted to dip into lubricating oil in the small receptacles 19,20 and 21 in the cover 22 of the lower crank case, which cover is held in place by means of screws 24- are threaded into the lower cover reinforcing bar 25. A gasketQfi is usually placed between the lower case and cover.

The rear ends of the upper and lower casesare expanded to make room for. the fly-wheel 27, magnet carrier 28 and the tionary magnet support 29, shown conventionally in Fig. 1, and also to constitute the main oil receptacle 30. lit has been found that when the engine 1s running, a heavy mlst of 011 fills the entire case, and that this -mist is much heavier at the rear end than at the front end when the vehicle is moving. An oil pipe 32 extends into the magneto sup port andis provided with a funnelfl?) to ceive the oil that is carried up by the fly wheel 27 and the magnet carrier, and this oil flows to the front end of the lower and into the front auxiliary receptacle lit, whence it is splashed u against the Walls of the case and into the ore of the forward cylinder by means of the connecting rod 13.

When the vehicle runs on a level road, the

oil fills the lower ease up to the top oi? the reinforcing bar 25, which results in cases.

sive lubrication of the cylinders. The oil. finally runs over the rear transverse portion of this bar into the main oil receptacle 30.

When the vehicle runs'down hill, the front end of the case fills with oil and sive quantity is splashed up by ti ing rod. 18, causing excessive l the front cylinder while the thn cylinders may result more seriously.

, from the sheet 35, being employed to m The present invention is -embodied in means for preventing excessive accumulao tion of lubricating oil'in the case, especially.

at any particular point thereof beneath the cylinders, by conveying this oil toward the rear and into the main receptacle.

The preferred form consists of a resilient sheet of suitable metah secured in place by of bolts 86, the nuts being on the outside and small lips 38, struck up vent the bolts from turning. This sheet is formed with troughs 39 which slope downwardly toward the rear so that the oil splas up out of auxiliary receptacle flow to the auxiliary receptacle 20,

r I. and on until at rear end the oil will be conducted to the main receptacle '30. If

there were no troughs to conduct the oil splashed up by the connecting rod 1? over and beyond the rear transverse portion of the. reinforcing bar 25, the troughs between the receptacles 19 and 20,- and between the" receptacles 20 and 21 would be inciiective as the oil would stand above the bottom of the cover 22 and immediately liow forwardfrom one auxiliary receptacle to the other.' But by conductingthc oil splashed up by the connecting rod 15 to the main receptacle 30, the excess ve lubrication because of the depth of oil above the covcr22 is entirely avoided and a continuous flow of'oil to the. splashed 'up to adjacent auxiliary recepmain receptacle in the rear is produced.

The sheet 35 is preferably made of sufficient length to extend from opposite the :5 out receptacle 19 to or j ust beyond the rear or the transverse portion of the reinfo'cing bar 25, so that the oil will fiow into main receptacle 30 it may be held in p01 ion by being formed a trille flatter than ehown in Fig. 3, and then be drawn down to final position by means of the bolts 36. Or small lingers 41 (Fig.5) may be secured to the sheets so that their lower ends will extend down be. .ind the reinforcing bar 25. Gr small brackets 42 of sheet metal (Fig. l.) may secured to the sheets and-fit the .ln order to position the holes for the bolts 38, a templet 45 such as shown in Fig. 11 be employed. The cover 22 being r moved, the templet secured in position on outside of the lower case by means of the screws 24 passing through the holes 46 and into their regular holes in the bottom case 3 and bar The holes for the bolts 5 26 may then be marked'through the holes 4.? the templet, or the templet may be niea eoe a jig, as wellyfor guiding the discharge was 53, while the rear troughs 52 extends just above the reinforcing bar 25. This structure may be held in position by screws 54:; whose proper positions may be determined by a templet 45. It will be understood that these troughs may be secured to bothside's of the crank case, as indicated in Fig.3,- and that the length may bevaried-so as to adapt this invention to engines or any 'numbeu of cylinders, so long as a mum oll receptacle has an oil receiving portion or' opening-at the discharge end of these troughs. Itwill be understood that this present invention does not include the location or structure of the main oilreceptacle, which maybe of any desired form'locatcd in any convenient position. H
